1. Remove the main circuit connector and motor connector from the servo drive.
2. Peel off the cladding of the used wires.
3. Use a tool to open the wire insertion part of the terminal connector. There are two methods of opening. You
can choose any of them.
①Use method of spring opener
②Use method of flat screwdriver
The opening operation is performed using a
spring opener as illustrated
As shown in the figure, insert a flat-blade
screwdriver into the screwdriver insertion opening
to open the wire insertion part.
4. Insert the core wire part of the wire into the wire insertion part. After insertion, pull out the spring opener or a
slotted screwdriver.
5. Repeat the above operations and make necessary connections.
6. After wiring is completed, install the connector to the servo drive.
4.3.3 Power on sequence control
Please consider the following points when designing the
power on sequence control.
 After the control power is turned on, the servo alarm
output (ALM) signal is output within a maximum of 5.0
seconds. Please consider it when the power on
